Rental property investing in Delaware: cash flow, taxes, and what to expect

The Delaware setup, at a glance

Delaware sits at roughly 0.61% effective property tax, which matters more than most new investors realize. On a $220k-$310k Wilmington property, that's about $1,342/year in taxes alone - call it $112/month before you've paid anything else. Run the rental cash flow calculator with that line item baked in or your projection will look better than reality.

Eviction stance here is balanced. Balanced. 5-day notice, JP court hearing 10-30 days. That timeline directly affects your vacancy assumption: in balanced-friendly states like Delaware, you can underwrite 5-7% vacancy on B-class properties; in slower states you'd want 8-10%.

Where the math actually pencils

Wilmington - $220k-$310k for typical SFR, $1,300-$1,750/mo for 2-3BR rents. banking + corporate domicile, stable.

Dover - $240k-$330k for typical SFR, $1,350-$1,750/mo for 2-3BR rents. Air Force base + state govt.

The 1% rule (monthly rent >= 1% of purchase) is a smoke test only, but it filters fast: a $240k-$330k property in Dover renting at the high end (1,750/mo) clears 0.8-0.9% in most cases, so you're already in the "needs the rest of the math to be tight" zone before vacancy + capex + management.

Delaware-specific things that bite

No sales tax. Beach property in Sussex County is a separate STR market.

A few cash-flow-killer line items that catch out-of-state buyers in Delaware:

• Property tax escrow. Lower than the national 1% average, but the homestead exemption you'd get as an owner-occupant doesn't apply to rentals.
• Insurance. Standard hazard policies are still reasonable here, but ask about wind/hail riders depending on the specific zip.
• PM costs. 8-10% of collected rent is typical. On a $1350/mo property that's $122-135/mo - works out to about a month of vacancy each year.

What "good enough" looks like in Delaware

For a stabilized buy-and-hold in Delaware, the rule-of-thumb deal targets most investors I see are:

• Cap rate: 6%+ on the actual NOI (not the broker's pro forma). Below 5% and you're paying for appreciation, which is fine if that's your thesis.
• Cash-on-cash: 8-10% minimum at year 1 with 20-25% down. 12%+ is solid for the work.
• DSCR: 1.25+ if you're using a DSCR loan. Lenders increasingly want 1.2 as a floor, 1.25 to clear comfortably.
• Reserves: 6 months of PITI. Delaware's slower eviction process means you may need 8-9 months of reserves in a worst-case turn.

The play that works here

Delaware has tilted toward appreciation rather than cash flow in most major metros. Cash-flow seekers usually need to look at secondary cities or accept lower CoC for the appreciation thesis.

Run your specific deal through the rental calculator with the state's effective tax rate (0.61%), realistic Delaware insurance quotes, and 8-10% PM. If it still pencils after that, you've got a deal.
